What is a baby oxygen monitor?

A baby oxygen monitor, often referred to as a pulse oximeter for infants, is a device designed to measure the oxygen saturation levels (SpO2) in the blood and heart rate of a baby. These small, non-invasive devices are particularly useful for monitoring babies with respiratory issues, heart conditions, or for those who are at risk for sudden infant death syndrome (SIDS) and other sleep-related conditions.

The device typically works by attaching a sensor to a part of the baby’s body, such as a foot or hand. This sensor uses light to measure how much oxygen is being carried in the blood, as well as the baby’s pulse rate. The information is then displayed on the monitor, allowing parents or caregivers to keep track of the baby’s oxygen levels and heart rate in real time.

Baby oxygen monitors can be found in various forms, including standalone units or as part of a more comprehensive baby monitoring system that may also track other parameters like temperature, movement, and sound. Some models are designed for use in hospitals or clinical settings, while others are intended for home use, offering parents peace of mind that their baby is breathing well during sleep.

It’s important to note that while baby oxygen monitors can provide valuable information about a baby’s well-being, they are not a substitute for professional medical advice. Any concerns about a baby’s breathing or health should be discussed with a pediatrician.

Owlet introduced this monitor in 2015 with the first-generation Owlet and has since improved it with 3 subsquent versions with the latest version being the Dream Sock. Read about Owlet 1,2, and 3 here and find difference between Owlet Sock 3 and Dream Sock here.

Owlet Dream Sock is not just any breathing monitor; it is the overall best infant oxygen monitor on the market, offering unparalleled insights into your infant’s health via vital signs analysis and notifications. This FDA-cleared device is a game-changer for parents and caregivers, seeking to provide the utmost care for infants aged 1-18 months and weighing between 6-30 lbs.

In 2021, the Oxygen level monitoring feature of Owlet made FDA to claim that it is a diagnostic device and should be classified as a medical device. This led to a series of changes that led to Owlet removing instant oxygen alert notifications in the Owlet app upon its re-introduction in the market. However, after the FDA-clearance, and after app modification that made Owlet market it as a sleep quality monitor, instant oxygen level alerts were reinstated 5 months ago in November 2023.

When my infant had a bout of respiratory infection, my anxiety about their well-being, especially concerning their breathing and oxygen levels during the night, was at an all-time high. This period was particularly challenging, given the constant worry that enveloped my nights. That’s when the Owlet Dream Sock became an indispensable tool in our household, providing not just reassurance but an active monitoring system for those crucial overnight hours.

One night, in the wee hours of the morning, the value of the Owlet Dream Sock was put to the test. After a long day, both my baby and I had finally settled down for some much-needed rest. The Owlet was snugly fitted to my baby’s foot, continuously monitoring their oxygen saturation and pulse rate, with the data being sent in real time to both the Base Station in my bedroom and the Owlet Dream App on my smartphone.

Suddenly, around 2 AM, the calm of the night was interrupted. The Base Station emitted a series of lights and sounds, while simultaneously, my smartphone vibrated with an alert from the Owlet Dream App. My heart skipped a beat as I sprang from my bed and rushed to my baby’s side. The alert indicated that their oxygen levels had dipped slightly below the normal range.

Upon reaching my baby, I found them in a slightly awkward position. Gently, I adjusted them, and almost immediately, I could see an improvement in their breathing. Monitoring the Owlet Dream App, I watched in real-time as the oxygen levels began to climb back to the safe zone. The alert ceased, both on my phone and the Base Station, signaling that everything was once again okay.

Reflecting on this experience, the peace of mind and the level of active monitoring the Owlet Dream Sock provided were invaluable. Without it, I might have remained unaware of the critical drop in my baby’s oxygen levels, missing a potentially crucial moment to intervene. The Owlet Dream Sock didn’t just monitor; it alerted me at a critical moment, allowing me to act swiftly to ensure my baby’s well-being. For any parent, the reassurance that comes from knowing you have an extra set of “eyes” on your baby’s health through the night is priceless.

In terms of accuracy, the Owlet has largely lived up to its promise. The readings align well with the pediatrician’s measurements during check-ups, which speaks volumes about its reliability. However, it’s not without the occasional false alarm—mostly when the sock gets slightly displaced due to my baby’s movement. While initially startling, I’ve learned to quickly check on my baby and the sock’s placement before letting panic set in.

In fact this monitor doesn’t allow you to set the normal Oxygen level saturation range but does let you set the range for heartbeat as shown in the app set-up snapshot below;

Eufy smart sock doesn't have live push notifications for low oxygen levels.

This brings me to my next point.

While Owlet faced FDA’s stringent requirements and subsequently made significant efforts to comply with the requirements, Eufy seems to have easily copy-paste the work of Owlet and introduced the product to market at a far cheaper price – about $100 less than Owlet’s Dream Sock?

How could they do it?

The technology called pulse oximetry used by Owlet was invented back in 1940s and there isn’t really any other significant technology that Owlet made in their sensors other than the design of the sock. While I was able to find patents filed by Owlet dating back to 2013, most of them were around the sock design and others were slight variations of existing patents. This made it easy for any other manufacturer to slightly modify the Sock design and not face any patent infringments. Here are all patents assigned to Owlet.

Eufy isn’t the only company that modified the Sock and released it in the market. Others include Wellue,

What Eufy really wins is in its ease of use with very quick set-up process and less hassle trying to configure the Sock and the Cam 2 to WiFi. I found it much less involving compared to Owlet that at times let out very loud warnings that are totally unnecessary.

Why Low Oxygen Level is a Serious Health Concern:

Low oxygen levels in a baby can be a crucial concern for several reasons, as oxygen is essential for the proper functioning and development of all bodily tissues, especially the brain and heart. In infants, maintaining adequate oxygen levels is vital for their overall health and development. Here are key reasons why low oxygen levels (hypoxemia) can be particularly critical for a baby:

  1. Brain Development: The brain is one of the most oxygen-dependent organs in the body. Adequate oxygen supply is crucial for normal brain development and function. Low oxygen levels can lead to hypoxic injury, where brain cells are damaged or die, potentially resulting in developmental delays, cognitive impairments, or other neurological issues.
  2. Cardiovascular Health: Oxygen is necessary for the heart to function correctly. Hypoxemia can strain the cardiovascular system, as the heart must work harder to deliver the limited oxygen available to the rest of the body. Over time, this can lead to complications such as heart failure or other cardiac conditions.
  3. Growth and Development: Oxygen plays a vital role in metabolism and energy production, which are essential for growth and development. Low oxygen levels can impede these processes, potentially leading to growth retardation or failure to thrive in infants.
  4. Increased Risk of Infections: Adequate oxygenation is necessary for a robust immune response. Hypoxemia can weaken the immune system, making infants more susceptible to infections, which they are already at a higher risk for due to their developing immune systems.
  5. Respiratory Distress: Low oxygen levels can be both a cause and a consequence of respiratory distress. Conditions that lead to respiratory distress, such as bronchiolitis or pneumonia, can further decrease oxygen levels, creating a vicious cycle that exacerbates the infant’s condition.
  6. Sudden Infant Death Syndrome (SIDS): While the exact cause of SIDS is unknown, research suggests that abnormalities in the part of an infant’s brain that controls breathing and arousal from sleep may contribute to sudden death. There is speculation that low oxygen levels might play a role in some cases, though the relationship is not fully understood. Read more on this Boston Children’s Hospital blog.

How top-rated oxygen monitors work:

Pulse oximetry is the technology behind baby oxygen level monitors, a non-invasive method used to measure the oxygen saturation level (SpO2) of the blood and heart rate. This technology is widely used in medical settings and has been adapted for use in monitoring infants at home or in hospitals. Here’s how pulse oximetry works, broken down into its basic components and mechanics:

Principle of Operation

  1. Light Emission: The pulse oximeter uses a sensor that emits light from light-emitting diodes (LEDs). This sensor typically emits two wavelengths of light, one in the red spectrum (around 660 nanometers) and the other in the infrared spectrum (around 940 nanometers). These two wavelengths are chosen because oxyhemoglobin (oxygenated hemoglobin) and deoxyhemoglobin (deoxygenated hemoglobin) absorb light differently at these wavelengths.
  2. Light Detection: After the light is emitted through the body part, usually a thin part such as a baby’s fingertip or toe, a photodetector on the opposite side of the sensor detects the amount of light that has passed through. The amount of light absorbed by blood varies depending on the blood’s oxygen saturation; oxygenated and deoxygenated blood absorb different amounts of red and infrared light.
  3. Calculation of Oxygen Saturation: The pulse oximeter calculates the ratio of the absorption of the red and infrared light to determine the SpO2 level. This calculation is based on the different absorption spectra of oxyhemoglobin and deoxyhemoglobin. The device uses a predetermined algorithm to estimate the percentage of hemoglobin in the blood that is saturated with oxygen, based on the absorption of these two wavelengths of light.
  4. Pulse Detection and Heart Rate Calculation: The device also detects the pulse by measuring the changes in light absorption that occur with each heartbeat. These changes are due to the pulsatile nature of blood flow, which causes slight variations in the volume of blood in the tissue during the cardiac cycle. By analyzing these variations, the device can calculate the heart rate.

Key Features for Accuracy

  • Placement and Fit: The sensor must be properly placed and fit snugly (but not too tightly) on a suitable body part, like a baby’s foot or hand, to ensure accurate measurements.
  • Motion Tolerance: Modern pulse oximeters, especially those designed for babies, often incorporate technology to minimize errors due to movement, which is a common issue when monitoring infants.
  • Skin Integrity and Perfusion Level: The device’s accuracy can be affected by the skin’s condition and the blood perfusion level of the monitored site. Good perfusion is necessary for accurate readings.

Safety and Non-Invasiveness

  • Pulse oximetry is a safe and non-invasive method. It does not require a blood sample or any invasive procedure, making it particularly suitable for continuous monitoring of infants without causing discomfort or harm.

Pulse oximeters for babies are specifically designed to account for the small size and greater movement of infants, ensuring that parents and caregivers can reliably monitor their oxygen saturation levels and heart rates with minimal intrusion.

Concentration Explained:

The oxygen concentration, or oxygen saturation level, in a baby’s blood is an important measure of how well oxygen is being transported to all parts of the body vital for proper organ and tissue function. Oxygen saturation is expressed as a percentage (SpO2) that reflects the amount of oxygen-carrying hemoglobin in the blood relative to the total hemoglobin that could potentially carry oxygen. Here’s a breakdown of what the figures generally mean:

Normal Range

  • 95% to 100%: This is considered a normal range for healthy babies, both awake and asleep. It indicates that a sufficient amount of oxygen is being carried to the tissues throughout the body.

Mildly Low

  • 91% to 94%: This range can be a sign of mild hypoxemia, indicating a slightly lower than ideal oxygen level in the blood. It may require monitoring and possibly further evaluation to determine the cause, especially if it persists.

Potentially Concerning

  • Below 90%: Oxygen levels below 90% are generally considered low (hypoxemia) and potentially concerning. This condition requires immediate attention to determine the cause, as prolonged periods of low oxygen saturation can lead to inadequate oxygen supply to the body’s tissues and organs, potentially resulting in complications.

Special Considerations for Newborns

  • In the first few minutes after birth, it’s normal for a newborn’s oxygen saturation to be lower. Normal SpO2 levels are expected to increase gradually from about 60% to 65% at one minute after birth to 85% to 95% by five minutes after birth. Full-term healthy newborns typically reach levels above 95% shortly thereafter.
  • Preterm babies or those with respiratory distress might have different target ranges, especially in a neonatal intensive care setting. These targets are often determined by clinical guidelines and individual circumstances.

Context is Key

  • It’s important to consider the context and the baby’s overall health condition when interpreting oxygen saturation levels. Factors such as altitude (higher altitudes have lower normal SpO2 values), existing health conditions, and whether the baby is breathing room air or receiving supplemental oxygen can influence what is considered normal or acceptable.

Monitoring and Action

  • Continuous or regular monitoring using a pulse oximeter can help track a baby’s oxygen levels, especially if they have underlying health conditions or are showing signs of respiratory distress. Any concerns or abnormal readings should prompt consultation with a healthcare provider to ensure appropriate evaluation and intervention.

Oxygen concentration figures are crucial for understanding a baby’s respiratory and circulatory system health. Accurate and timely monitoring can help in early detection of potential issues, guiding interventions to maintain optimal health.

Low Oxygen Saturation:

Low oxygen saturation, also known as hypoxemia, occurs when the level of oxygen in the blood is lower than normal. Oxygen saturation is a measure of the amount of oxygen-carrying hemoglobin in the blood compared to the total hemoglobin that could be carrying oxygen. It’s an important indicator of how effectively oxygen is being transported to the tissues and organs throughout the body.

Understanding Oxygen Saturation Levels:

  • Normal Range: For healthy individuals, a normal oxygen saturation level (SpO2) is typically between 95% and 100%. This indicates that most of the hemoglobin is carrying oxygen.
  • Low Oxygen Saturation: Levels below 90% are considered low and indicate hypoxemia. Mild cases might show levels between 91% and 94%, but levels below 90% are more concerning and often require medical attention.

Causes of Low Oxygen Saturation:

Low oxygen saturation can be caused by a variety of factors, including:

  • Respiratory Conditions: Diseases like chronic obstructive pulmonary disease (COPD), asthma, bronchitis, pneumonia, and pulmonary edema can restrict airways or damage lung tissue, reducing oxygen absorption.
  • Cardiac Conditions: Heart problems, including congenital heart defects and heart failure, can impair the heart’s ability to circulate oxygen-rich blood efficiently.
  • Altitude: Higher altitudes have lower oxygen levels in the air, which can lead to lower oxygen saturation levels in individuals not acclimated to high altitudes.
  • Sleep Apnea: This condition causes periods of stopped breathing during sleep, leading to temporary drops in oxygen saturation.
  • Anemia: A lower than normal number of red blood cells or hemoglobin can reduce the blood’s oxygen-carrying capacity.

Symptoms of Low Oxygen Saturation:

Symptoms may vary based on the severity of the oxygen deprivation and the underlying cause but can include:

  • Shortness of breath or difficulty breathing
  • Rapid breathing
  • Coughing or wheezing
  • Increased heart rate
  • Confusion or disorientation
  • Fatigue or weakness
  • Bluish color in the skin, lips, or nails (cyanosis)

Implications and Treatment:

Prolonged or severe hypoxemia can lead to complications because organs and tissues need adequate oxygen to function properly. Treatment depends on the underlying cause but may include:

  • Supplemental Oxygen: Providing extra oxygen through a mask or nasal cannula to increase blood oxygen levels.
  • Medications: To treat underlying conditions, reduce inflammation, or open airways.
  • Lifestyle Changes: Such as quitting smoking or avoiding exposure to pollutants.
  • Surgery or Procedures: In cases related to structural issues in the heart or lungs.

It’s important to address low oxygen saturation promptly, especially if symptoms are present or if the individual has an underlying health condition that could worsen with reduced oxygen levels. Medical evaluation and treatment are essential to manage hypoxemia and its causes effectively.
